The Computational and Modelling Services (CMS) unit of the Models and Data division of the ​National Centre for Atmospheric Science (NCAS) provides computational modelling services to the UK academic atmospheric and polar science community to support numerical modelling in climate, weather, and earth-system research.

The main remit of CMS is to provide a range of services for the environmental modelling community, which include:

Managing users and usage on national platform for the atmospheric and polar science consortium of the NERC HPC community.

Managing infrastructure to support modelling workflows, including code managements systems, and job management and submission systems for the Unified Model.
